Everyone at some point has talked about their mouse sensitivity, DPI etc, but keyboard settings seem to go overlooked, there's a simple setting that can help alot with zerg and terran macro.
On windows7 and XP, just open the control panel and search for 'keyboard',
open that and change the 'repeat delay' to the shortest possible.
Now, when you queue up marines on multiple barracks or want to use 17 larvae, the delay between each keystroke being recognised when you hold down A or R is now reduced.
